Which part of the pH scale is acidic?
Correct Answer:
0 to 6
Explanation:
Acidity on the pH scale is represented by values below 7. Since pH is a measure of hydrogen ion concentration, lower pH means higher acidity. The range from 0 up to 6 sits in the acidic region, with 7 being neutral and values above 7 being basic. So the part of the scale that is acidic is 0–6. The other options point to neutral (7), basic (8–14), or the entire range (0–14) which isn’t specifically acidic.
